From bf3f204b92c48c4afa3e827dfe98353560d9aa7f Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Thu, 15 Sep 2011 14:25:37 +0200 Subject: [PATCH] ath9k_hw: fix setting the hardware diversity flag ath9k_hw_set_diversity is only called from init.c where it cannot affect the hardware setting because it's cleared on the next reset. Instead of using a PHY op for something that's supposed to be initialized statically, set the register value directly in the INI override function. Signed-off-by: Felix Fietkau Signed-off-by: John W.
